Image Transmission System with Adaptive Bit Precision Control

The patent applies local quality by differentiating encoding precision across different image regions. Important regions (e.g., areas with edges, textures, or semantic significance) are encoded with high precision to maintain gradation, while less important regions use lower precision encoding. This resolves the contradiction by maintaining image quality where needed while reducing overall encoding amount through selective precision application.

The patent segments the image into multiple regions with different encoding requirements. By dividing the image and applying different quantization parameters to different segments, the system achieves both high gradation preservation in critical areas and reduced encoding amounts in non-critical areas, thereby resolving the contradiction between image quality and encoding efficiency.

The patent implements dynamic encoding by allowing the encoding parameters (particularly quantization step widths) to change based on the specific application and image content. The system can adaptively adjust encoding precision according to different processing modes (e.g., monitoring, recognition, transmission) without requiring completely different encoding systems, thus achieving application adaptability while controlling complexity through a unified adaptive framework.

The patent utilizes parameter changes by modifying encoding parameters (such as quantization step widths and bit allocation) based on application requirements and image characteristics. This allows the same encoding system to adapt to different applications by changing parameters rather than structure, achieving versatility while maintaining relative simplicity through parameter-based flexibility.
